Chirag : You could put an entry in rc.local (refer a script) to send a mail with all the logs /var/log/messages o/p of last o/p of history o/p of df -k
For this u will need to configure sendmail as client on all servers..! This shd help u receive a mail every time reboots..! Also install tripwire to find any intrusions or changes in the files..! Harden ur servers before u put them in production..! u shd comment out ctrlaltdel in /etc/inittab it might be possible that somebody pressed Alt+Ctrl+Del on the console..!
